Depending on how long or often they run, the furnace blowers, on a cold night, can put a serious hurt on the batteries.
On a recent trip it was chilly & windy with a morning temp of 27F. I knew it was time to get up because I could hear the furnace blower click but not blow. A minute or so later it would repeat. Batteries were at 7.3V (2 6V cells). Thank God for that jumper switch to crank up the generator!
A typical "at rest" voltage would be 12.4V a few hours after charging, and that's from the dash meter, which might not be accurate. Is there any wisdom for when it's time for a bank of batteries to hit the trail? I have a DVM and ball tester but that only indicates current (no pun) state of charge.
Winter is the biggest draw. Now I have 8 months to put it off!
